Replacement for ThinkPad T450s and X240
This 6-cell lithium-ion battery replaces original Lenovo part numbers 0C52861, 0C52862 and the 45N1124 series. It fits a wide range of models including the T440, T460, T470p, T550, T560, W550s and X250. Buyers who need a higher-capacity 9-cell pack or a battery for newer ThinkPad generations will not find a match here.
Sustained discharge and smart-chip control
The integrated control chip manages charging current to reduce heat buildup during long sessions and extends discharge time under steady load. Protections against short circuit, overheating and overload activate automatically when limits are reached. The 4400mAh capacity at 10.8V delivers 48Wh of energy for typical office workloads.
Thermals, noise and power draw in normal use
Lithium-ion cells generate no acoustic noise and the pack runs at ambient temperature during standard charging and discharging cycles. The smart chip lowers power consumption while idle, helping the battery retain charge when the laptop is asleep. No active cooling is required and the unit adds no audible component to the system.

Questions about this item
Does the 6-cell 10.8V 4400mAh pack run hot or draw extra power during a full workday?
The lithium-ion cells and built-in smart chip are designed for efficient discharge and lower power consumption, keeping heat in line with the original 48Wh specification.
What must I already own for this MPL10241P-29 battery to work in my ThinkPad?
You need a compatible Lenovo ThinkPad such as the T440, T450s, T460, T470p, T550, T560, W550s, X240 or X250, and the original battery must match part numbers like 45N1124, 45N1125 or 45N1126.
Will this 10.8V 6-cell replacement fit and charge correctly in an older X240 that currently uses a 45N1124 battery?
Yes, the MPL10241P-29 matches the 10.8V 4400mAh 48Wh spec of the 45N1124 and is listed as compatible with the X240, so it will seat and charge normally.
